Decision

What the current evidence supports

Agent-assisted assessment · independently reviewed · 2026-10-01

Evaluate original WSE-3 for supported workloads with demanding latency or local communication needs.

Why
Independent physical experiments demonstrate useful capabilities, with substantial software constraints and workload-dependent performance.
Next
Benchmark the exact CS-3 configuration, model, batch size and numerical requirements, including transfers, compilation, power and operating costs.

Constraints

Blockers

  • Specialized programming and compiler constraints increase development effort.
  • Model and batch-size support require configuration-specific checks.
  • Small workloads can underutilize the wafer.
  • Kernel benchmarks can omit transfers and initialization.
  • Published experiments do not establish production uptime or large-cluster reliability.
  • Current cloud performance claims may concern Turbo or CS-4 hardware.
